0Wal-mart Grapples With RFID: 1. Describe some RFID applications that might pose a threat to privacy. What information does RFID enable them to track? RFID is a type of an automatic identification system that enables data to be transmitted by a portable device, called a tag, which is read by an RFID reader and processed according to the needs of a particular application. Because of their inconspicuous nature, these tags are not really visible and may pose a threat since people are not aware that they are carrying those tags or that someone might be reading information from them.
Making cyber bullying a criminal offense would be a ridiculous and near impossible task. Not only would convicting a cyber bully be extremely difficult, but more importantly, making cyber bullying a crime would not reduce the damage caused by bullying. My first contention is that it would be extremely difficult to convict a cyber bully of their crime. According to Jonathon Strickland; Discovery News; April 1, 2010, “Cyber bullying is just an extension of classic bullying and that it should be handled on the local level. This proves that there is almost no defined difference between cyber bullying and regular bullying, so it should be handled as if it were regular bullying.
Deep Freeze cannot be uninstalled by the simply manual operation. We need the password to uninstall it, which is generated at the time of downloading the software program. If we cannot remember the password, then we will not be able to uninstall the program. Most of the time, we forget the password and then we cannot uninstall the application. So, we need something different for uninstalling the program.
For example, avoid allowing a website to remember your password. If your password is stored, your profile and any account information you have provided on that site is readily available if an attacker gains access to your computer. Also, evaluate your settings on websites used for social networking. The nature of those sites is to share information, but you can restrict access to certain information so that you limit who can see what (see Staying Safe on Social Network Sites for more information).” (McDowell,
According to Larry Greenemeier, a recent court case, Carpenter V. United States "specifically pits the privacy of information that wireless devices share with their service providers-the towers or " cell sites" devices connect to, the phone numbers they call and answer, and the time and length of those calls-against law enforcement's authority to retrieve that data without a warrant." However, the FBI issued court orders under the 1986 SCA in order to compel carriers to turn that information over to the FBI. This would be acceptable despite the fact that a warrant requires more reasoning to receive. If they felt strongly enough that they had reason to obtain certain information, they should have to convince a judge to see the situation from the same point of view. “ Without a warrant, but with the SCA court order in hand-the FBI compelled MetroPCS to provide about four months of location records for a smartphone owned by suspect Timothy Ivory Carpenter.” Based off of the information the authorities had previously, it would not have been hard to convince a judge to issue them a warrant.
